If it’s too loose, the door won’t stay open. But if
it’s too tight, you’ll have a hard time using either the
internal or external release to close the door.
Over time, and with the constant vibration generated
during operation, the tension on the lock release can
change. If you notice problems with the release being
too loose or too tight, notify your mechanic.
O
perators who are used to the M88A1 recovery vehicle may have a harder time
using the main winch on the M88A2.
On the M88A1, you could use the winch from just about any angle. Not so with the
A2. It comes with sensors installed that will shut down the winch if you try to recover
a vehicle more than three degrees off center. And if your vehicle has Mod II installed,
the winch will pull only up to 8,000 pounds in this situation, even when in override.
Not understanding why the winch won’t work, many operators hook up to the
vehicle being recovered and try to pull it out by backing up the M88A2. That frays
the cable against the front cone (trumpet). Eventually, the entire cable has to be
replaced.
You can prevent all those problems by using your recovery vehicle the way it was
meant to be used. Take the few extra seconds needed to line up so that the winch will
pull the disabled vehicle straight out.
Adjusting the tension
is a simple matter of
loosening or tightening
the hex-socket screw on
the door’s hold-open lock.
